randomized problem 3

An object travels a distance of 32 cm in 17.6 seconds from start to finish. If its acceleration is uniform and its initial velocity zero, then what are its average velocity, acceleration and final velocity?

32cm/17.6 seconds =1.818=2cm/sec for the average velocity

2cm/sec /17.6seconds =0.113for average acceleration

2+0.113(17.6)=3.98=4 as final velocity

You should have rounded off to 2 significant figures, but your procedure is fine so no problem here.
